Pro peg nerf bar probs on a blaster
 

As above right side ok left side tyre catches on full lock any ideas how to solve the issue?

what do you mean by full lock?

So you have nerf bars, and the right nerf bar is rubbing? You got them mounted right? Have a pic?

When it's on full to left side the tyre catches the bar

When whats on full??

When wheels are turned as far as they go to left

Photo please.... this could indicate a couple of things actually. One of which could be a damaged frame, another worn parts, another possible incorrect positioning of Bars..... a combination of any or alol of the above..... bent ball joint.... lord only knows without some visuals.... more than one picture please.... several angles and views... top down, front with and without the tire touching.... that kind of stuff.
